C++

The function of a program is usually implemented in many ways, what is the best program? For example, if you implement two programs of the same function, one button gives the result of the run, and the other takes a long time to wait, just like

You can create a struct in C + +, which is similar to creating a new data type, except that the data type can contain other data members, and his syntax is as follows:struct type_name{Member_type1 membe1r;Member_type2 Member2;} Object1,object2
